The people of Pakistan are ethnically diverse. They trace their ethnic lineages to many different origins, largely because the country lies in an area that was invaded repeatedly during its long history. Migrations of Muslims from India since 1947 and refugees from Afghanistan since the 1980s have significantly changed the demographics of certain areas of the country. The people of Pakistan come from ethnic stocks such as Dravidian, Indo-Aryan, Greek, Scythian, Hun, Arab, Mongol, Persian, and Afghan. Although an overwhelming majority of the people are Muslim, religion does not supercede ethnic affiliations. The people follow many different cultural traditions and speak many different languages and dialects.
Pakistan has a population of 169,270,617 (2007 estimate), yielding an average population density of 217 persons per sq km (563 per sq mi). The country’s population was increasing in 2007 at a rate of 2 percent a year. Only 35 percent of the people live in urban areas. 
A. Cultural Groups
Pakistan is a multilingual and multiethnic nation. Most of the people belong to one of the country’s five major ethnolinguistic groups: Punjabis, Sindhis, Pashtuns (Pakhtuns), Mohajirs (Muslims who migrated to the newly formed nation of Pakistan after 1947), and Baluchis. Ethnically distinct subgroups exist within each of these five categories. Overall, ethnic identity is multilayered and complex and may be based on a combination of religion, language, ethnicity, and tribe.
Not all of the ethnolinguistic groups are equally represented in the power structure of Pakistan. Mohajirs, Punjabis, and Pashtuns are the dominant groups, while Sindhis and Baluchis struggle to advance and protect their interests.
Punjabis constitute 58 percent of the population. They have diverse origins, but over the centuries they coalesced into a coherent ethnic group in the historic Punjab region and developed a common language, Punjabi. Today most Punjabis prefer to read and write in Pakistan’s official language, Urdu, and their language-based ethnic identity is relatively weak. Many Punjabis are farmers in the fertile valley of Punjab Province. Punjabis also predominate in the military and the federal government.
Sindhis constitute 13 percent of the population of Pakistan. Their traditional homeland is the province of Sind, where they maintain the country’s largest concentration of large landholdings. Sindhis are a predominantly rural people. They have a strong sense of linguistic and cultural pride and identity. They have a rich literary and folk tradition and prefer to read and write in their own language, Sindhi.
Pashtuns constitute 12.5 percent of the population. Pashtuns are divided into many tribes, and their tribal structure is egalitarian. Pashtuns follow a strict code of conduct known as Pashtunwali (“Pashtun Way”). Pashtun identity, including their interpretation of Islamic law, is formulated and guided by Pashtunwali. The code is based on the absolute obligations of providing hospitality and sanctuary, even to one’s enemies, and exacting revenge at all costs in the defense of one’s honor. The code also requires Pashtuns to abide by the decisions of the jirga (council of tribal leaders) in matters of dispute. Many Pashtuns have blue eyes and claim to be descendants of the European soldiers who fought for Alexander the Great in the region 2,000 years ago. They have a rich oral tradition in their ethnic language, Pashto, but many Pashtuns prefer to read and write in Urdu. Pashtuns are primarily farmers, livestock herders, traders, and soldiers in the Pakistan military. 
Baluchis constitute 4 percent of the population. Most Baluchis are nomadic, migrating wherever the desert-like conditions of their homeland, the Baluchistan Plateau, provide enough vegetation to raise their animals. Raising livestock, mainly sheep and goats, and selling their hides and wool is a way of life for the Baluchis. They also have apple, almond, and apricot orchards, and some grow wheat. Baluchi tribal organization is strictly hierarchical, and each tribe is headed by a sardar (tribal chief). Most Baluchis speak Baluchi (Balochi), a language that is similar to Persian. About one-fifth of Baluchis also speak Brahui, a Dravidian-derived language. Baluchis are the least educated and poorest segment of the population and are inadequately represented in government.
Mohajirs constitute about 8 percent of the population. They are Muslims who settled in Pakistan after the partition of British India in 1947. Unlike other cultural groups of Pakistan, they do not have a tribe-based cultural identity. They are the only people in the country for whom Urdu, the official language, is their native tongue. Mohajirs were the vanguard of the Pakistan Movement, which advocated the partition of British India in order to create the independent nation of Pakistan for Indian Muslims. After the partition, a large number of Muslims migrated from various urban centers of India to live in the new nation of Pakistan. These migrants later identified themselves as mohajirs, meaning “refugees” in both Urdu and Arabic. A large number of Mohajirs settled in the cities of Sind Province, particularly Karāchi and Hyderābād. They were better educated than most indigenous Pakistanis and assumed positions of leadership in business, finance, and administration. Today they remain mostly urban.
B. Political Regions
The ethnic groups of Pakistan are distributed according to their historical settlement in the region. The current political regions of Pakistan roughly correspond to the settlement patterns established long before the partition of British India in 1947, when Pakistan was created as a homeland for Indian Muslims. The four provinces are Punjab, the Muslim portion of the historic Punjab region; Sind, the traditional homeland of the Sindhis; the North-West Frontier Province, a small portion of the Pashtun tribal lands; and Baluchistan, a portion of the Baluchi tribal lands. The traditional homelands of the Pashtuns and Baluchis extend beyond the modern political borders, both provincial and national.
Punjab is the most populated province of Pakistan, with 72.6 million people (1998). Most of the people are Punjabis. The province contains most of the country’s largest cities, but the rural agricultural areas are also densely settled. The province is the second largest in area.
Sind is the second most populated province in Pakistan, with about 30 million people (1998). Its population is the most urbanized in Pakistan. Sindhis make up about 60 percent of the population of Sind, living mostly in rural areas. Mohajirs constitute the remaining 40 percent and live mostly in the province’s large cities. Sind is the third largest province in area.
The North-West Frontier Province (NWFP) has a population of 17.6 million (1998). The majority of the people are Pashtuns. The province is part of the historic Pashtun tribal lands, which extend throughout southern and southeastern Afghanistan and well into western Pakistan, including the Federally Administered Tribal Areas and northern Baluchistan. The NWFP is Pakistan’s smallest province in area. In the 1980s refugees from war-torn Afghanistan began to settle in the province. Refugee camps and rudimentary villages were set up in the border areas. A large number of refugees also established communities in cities such as Peshawar. Many became semipermanent residents of Pakistan because Afghanistan remained in a state of war through the mid-1990s. The majority of refugees were Pashtuns, facilitating their assimilation into the province’s population, in many cases through intermarriage.
Baluchistan is the most sparsely populated and least developed province of Pakistan. A majority of the 6.5 million (1998) people who live in Baluchistan are Baluchis. Pashtuns are the second largest ethnic group in the province. In recent years a large number of Afghan refugees have settled in Baluchistan. In area, Baluchistan is the largest province of Pakistan, covering nearly 40 percent of the country’s total territory. However, the province is an arid and inhospitable hinterland.
C. Principal Cities
Pakistan’s largest city is Karachi, the capital of Sind Province. It is the country’s only seaport and a major financial, industrial, and commercial center. It is also known as the ethnic melting pot of Pakistan. Lahore, the capital of Punjab Province, is Pakistan’s second largest city and a cultural and educational center. Faisalabad, in central Punjab, is the center of textile and fertilizer industries. Multan, the largest city in southern Punjab, has many ancient Muslim shrines, a huge fertilizer factory, and small cottage industries such as carpet weaving and pottery. Hyderabad, in Sind Province, is a manufacturing center with textile and glass factories, as well as a cultural center with museums, historic mosques, and a medical school. Peshawar, the capital of the North-West Frontier Province, is a busy, overcrowded frontier outpost and a hub of trade with Afghanistan. For centuries it served as a gateway and trading post between Afghanistan and Southeast Asia.
Islamabad is the capital of Pakistan and the seat of the federal government; it forms its own administrative unit, the Islamabad Capital Territory. Just to the south, in bordering Punjab Province, is Rawalpindi, the headquarters of the Pakistani army and an industrial center.
D. Religion
Islam is the faith of about 97 percent of the people of Pakistan. About three-quarters of the country’s Muslims are Sunni, and about one-quarter are Shia. Some small Muslim fringe sects, such as the Ahmedis and Zikris, also exist. Hindus and Christians form the largest religious minorities, accounting for about 3 percent of the population. Other religious groups include Sikhs, Parsis, and a small number of Buddhists. The constitution defines Pakistan as an Islamic state but guarantees freedom of religion.
E. Languages
Urdu is the official language of Pakistan. It is the first language of only a small percentage of the population, but it cuts across linguistic and provincial boundaries as the national language. More than 75 percent of Pakistanis can speak and understand Urdu. In urban areas about 95 percent of the people communicate in Urdu. Urdu replaced English as the official language in 1978.
Most Pakistanis speak at least two languages. A large segment of the population is trilingual, speaking English, Urdu, and an ethnic-based regional language. Punjabi, Pashto, Sindhi, Baluchi, and Brahui are the major regional languages. These languages have many regional dialects, including Saraiki, a widely spoken dialect of Punjabi. Regional languages are recognized as a potent force because language and ethnic identity are closely interrelated; even the national census categorizes groups according to their language, rather than their ethnicity. However, there is growing awareness among Pakistanis that for social mobility, national cohesion, and individual success, it is imperative to be fluent in Urdu and proficient in English.
Several factors contributed to the establishment of Urdu as the lingua franca of Pakistan. It was the language of the educated Muslims in northern India, who spearheaded the Pakistan Movement. Urdu helped foster a linguistic identity among Muslims in the region. Although similar to Hindi as a spoken language, Urdu uses a Persian-derived script and incorporates many Arabic words. Choosing Urdu as the national language provided a linguistic basis for the formation of a Muslim national identity. It also provided the country with a “neutral” language because Urdu does not have ethnic or tribal associations. Since the founding of Pakistan in 1947, state-controlled electronic and print media have promoted Urdu. In the public schools of the country, Urdu is the principal language of instruction.
